High availability and disaster recovery system architecture

Abstract

A system may include a first device to provide a uniform resource identifier (URI) resolution or routing service among a first data center and a second data center. The first device may provide a first failover service among devices associated with the first data center for a set of interfaces. The system may include a first set of devices and a second set of devices associated with a first application and a second application. The first device may provide a second failover service for the first and second sets of devices. The system may include a first database cluster to provide software or a service related to clustering another set of devices or providing a threshold level of availability for the other set of devices. The first database cluster may provide a failover service for the other set of devices.
